If your are diagnosed with jumpers knee and you did what the doctor said and it still hurts what else should i do?

Many options: There are many components to completely resolve jumpers knee-aka patellar tendonitis. Besides anti- inflammories (for an acute problem, not for long term management), a patellar tendon strap, ice, and physical therapy (to address the factors that caused it), other treatments for chronic pain are on the horizon. Nitro patches and prp are experimental, but are being used for refractory cases.

Physical Therapy: Depends on what your physician advised you to do. Many patients benefit from modalities which can be administered at physical therapy such as iontophoresis. Topical inflammatory medicine can also be useful. If all else fails, some people may be candidates for arthroscopic surgery to treat the condition.
